示范答案：
I can’t give you an absolute answer actually, because whether the free-time activities are good for children’s health or not really depends on what the activities are. For example, some sedentary activities are not good for children’s health, such as surfing the internet all day long or watching TV immoderately. But, when it comes to some active things, such as taking part in sports or having some educational visits, I firmly believe that they are extremely beneficial to children’s health.
